本研究是一个大规模的对比分析声学线索的分类在摩擦音发音的地方。迄今为止，还没有发现一个单一的指标来分类摩擦发音的地方具有高度的准确性。这项研究提出了频谱，振幅，和时间测量，涉及静态属性（频谱峰值位置，频谱矩，噪声持续时间，归一化振幅，和F2发病频率）和动态属性（相对振幅和轨迹方程）。虽然所有的线索（除了轨迹方程）一贯用于区分从nonsibilant摩擦音，目前的研究结果表明，频谱峰值的位置，频谱矩，以及归一化和相对振幅用于区分所有四个地方的摩擦发音。这些研究结果表明，这些静态和动态的声学特性可以提供强大的和独特的信息，所有四个地方的发音，尽管在扬声器，元音上下文和发声的变化。(C)2000年美国声学学会。【S0001-4966（00）02909-X】。
This study constitutes a large-scale comparative analysis of acoustic cues for classification of place of articulation in fricatives. To date, no single metric has been found to classify fricative place of articulation with a high degree of accuracy. This study presents spectral, amplitudinal, and temporal measurements that involve both static properties (spectral peak location, spectral moments, noise duration, normalized amplitude, and F2 onset frequency) and dynamic properties (relative amplitude and locus equations). While all cues (except locus equations) consistently serve to distinguish sibilant from nonsibilant fricatives, the present results indicate that spectral peak location, spectral moments, and both normalized and relative amplitude serve to distinguish all four places of fricative articulation. These findings suggest that these static and dynamic acoustic properties can provide robust and unique information about all four places of articulation, despite variation in speaker, vowel context, and voicing.
